Huh. My buddy back in Portland had a similar idea probably 8-years ago. Except instead of rolling up, it collapsed like an OG Boy Scout cup so it fit in the palm of your hand, and you could throw it in your pack. He had a few prototypes made that worked really well, but he lost interest in the project and never sold them.

Great idea and design. Front tire is still going to light you up. Not as badly, but nonetheless.
